Azure Blob 存储 - sp 是必需的。不能为空

Question

我在尝试使用 SAS 链接将文件上传到 Azure Blob 存储时遇到错误。它是一个身份验证错误，提示 sp 属性为空。奇怪的是 Sp 元素出现在 SAS Url 中。

这不可能是权限问题，因为我可以使用 ADF 使用相同的 SAS URL 上传文件。

网址

BlobEndpoint=https://####.blob.core.windows.net/####?sp=racwdl&st=2021-12-08T01:14:01Z&se=2022-02-28T09:14:01Z&spr=https&sv=2020-08-04&sr=c&sig=####

Stream file = new FileStream(fileToUpload, FileMode.Open);
                var blobServiceClient1 = new BlobServiceClient(endpointString);

请尝试将连接字符串更改为:

BlobEndpoint=https://####.blob.core.windows.net/####; SharedAccessSignature=sp=racwdl&st=2021-12-08T01:14:01Z&se=2022-02-28T09:14:01Z&spr=https&sv=2020-08-04&sr=c&sig=####
